August 1992 to presentCollections Manager and Head, Minerals, Carnegie Museum of Natural History. Responsibilities include: collections curation; specimen acquisition; maintaining and improving exhibits in Hillman Hall of Minerals and Gems; specimen identification; coordinating the public outreach of Minerals, including lectures, special exhibits for gem & mineral shows, preparing quarterly, yearly and special reports and interaction with the public; creation and management of the Carnegie Gem & Mineral Show; and managing all aspects of section business activities.

October 1988 to August 1992Mineralogist for New Mexico Bureau of Mines and Mineral Resources. Experience includes management of the Bureau’s Mineral Museum with responsibility for attendant public outreach and growth programs; management of the Bureau’s annual mineral symposium; simple to complex identification of rocks and minerals for public and industry; public relations, including talks to amateur and professional mineralogy groups; participation in investigations of abandoned mines and smelter sites to determine possible contamination or future economic merit; mineralogical research, including ore microscopy studies; and supervision of student employees.

March 1982 to October 1988Head of Geological Interpretation, GeoSpectra Corporation. Experience includes: lithologic, structural and geochemical mapping and base, precious and strategic metal and oil and gas exploration. Projects have utilized Landsat M.S.S., Landsat T.M., H.C.M.M., A.T.M., T.I.M.S., S.I.R. A and S.A.R. data in addition to traditional air photographs and geophysical data sets. Responsibilities include organization and evaluation of resources, choice of proper data sets and combinations of data channels and principal components of data channels for each project; literature review and evaluation; supervision of other geologists and geophysicists of the interpretation group; close interaction with computer programmers in software development and improvement; and image interpretation. Some work in crop discrimination was also performed.

June 1979 to March 1982Geologist, St. Joe American Corporation. Experience consists of geologic mapping, air photo and ERTS image interpretation, and prospect examination in Proterozoic and Archean terranes of Upper Michigan. This includes hard rock uranium with attendant geophysical surveys and drilling and greenstone gold and massive sulfide exploration. Geophysical examination and drilling of massive sulfide targets in the upper Midwest with special emphasis on winter drilling. Exploration within the Black Hills of South Dakota, including sampling, prospect generation, detailed and semi-regional mapping, and statistical analysis of large scale geochemical program. Most programs have involved long, independent, self-structured periods in the field (up to three months) with and without field assistants.

June 1976 to November 1978Geologist, Rioamex (spring, summer and fall months). Radiometric reconnaissance of Precambrian terranes in parts of Upper Michigan, Wisconsin, Minnesota and South Dakota. Massive sulfide and stratabound copper exploration including supervision of field crews of up to four in Michigan and South Dakota. Witwatersrand-type quartz pebble conglomerate exploration in Wyoming, South Dakota and Upper Michigan with attendant magnetic and radiometric surveys. Responsible for the mapping and sampling field crews, and siting, logging and supervision of diamond drill holes. Uraniferous rhyolitic tuffs in Utah and Oregon and uranium veins in the Colorado Rockies were also explored. Projects were largely self-structured with a minimum of supervision, and often involved coordination of field crews in mapping and sampling programs.
